Your plant has a calcium deficiency, I noticed your only giving her 1ml at this stage she needs at 3 or 4ml of Cal-Mag instead, up that and she'll be fine.

Yep, calcium. Either too little calcium or PK nutes locking out the micros. You should know which is most likely.

Saw this first day of 12/12
Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

I water my plants everyday , however I have mixed my nutrients “ph perfect grow, micro, and bloom” in with my water only the appropriate amount given on the bottle. Should I be using water with the nutrients everytime I water or switch it up with plain water as well?

Any suggestions on what you think the problem could be with #2 could be welcomed. Air pots, soil dries out 2-3 days, temps stay in same range, since sick no training was done, brown spots starting at old growth and moves up plant on big fan leaves 1st then rusty look as progress?

Yellow/ brown leaves #2 (pics didn’t post the 1st time)
Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks
